“…The most commonly commercialized semiconductors are binary oxides such as titanium dioxides (TiO2, CAS: 13463-67-7) or zinc oxides (ZnO, CAS: 1314-13-2) . For example, 270 patents registered for ceramic roof tiles include the use of binary oxides for photocatalysis (Ranogajec and Radeka, 2013). For example, this is the case with Erlus Lotus air® tiles, which are coated with TiO2 to reduce nitrogen oxide pollution ("Erlus Lotus Air®," n.d.).…”

“…• 5.4 Advantages and drawbacks One of the significant advantages of photocatalysts, compared to biocides or waterrepellents, is that they resist the firing along with the industrial production of building materials (i.e., around 1,000°C for ceramic roof tiles). Thus, they can be added during the manufacturing process, and their usage does not need an additional coating step at the end of fabrication (Gladis et al, 2010;Gladis and Schumann, 2011;Ranogajec and Radeka, 2013), facilitating the industrialization of antifouling solutions based on photocatalysts. Moreover, photocatalysts and especially TiO2, are very stable over time (Hashimoto et al, 2005) and thus have shown suitable antimicrobial activity and prevent biodeterioration over a long time (Dyshlyuk et al, 2020).…”

All types of building materials are rapidly colonized by microorganisms, initially through an invisible and then later a visible biofilm that leads to their biodeterioration. Over centuries, this natural phenomenon has been managed using mechanical procedures, oils, or even wax. In modern history, many treatments such as high-pressure cleaners, biocides (mainly isothiazolinones and quaternary ammonium compounds) are commercially available, as well as preventive ones, such as the use of water-repellent coatings in the fabrication process. While all these cleaning techniques offer excellent cost-benefit ratios, their limitations are numerous. Indeed, building materials are often quickly recolonized after application, and microorganisms are increasingly reported as resistant to chemical treatments. Furthermore, many antifouling 5 compounds are ecotoxic, harmful to human health and the environment, and new regulations tend to limit their use and constrain their commercialization. The current state-of-the-art highlights an urgent need to develop innovative antifouling strategies and the widespread use of safe and eco-friendly solutions to biodeterioration. Interestingly, innovative approaches and compounds have recently been identified, including the use of photocatalysts or natural compounds such as essential oils or quorum sensing inhibitors. Most of these solutions developed in laboratory settings appear very promising, although their efficiency and ecotoxicological features remain to be further tested before being widely marketed. This review highlights the complexity of choosing the adequate antifouling compounds when fighting biodeterioration and proposes developing case-to-case innovative strategies to raise this challenge, relying on integrative and multidisciplinary approaches.

“…Since the degradation processes start on the material surface, the deposition of suitable protective coating can change and improve the surface properties, resulting in a moderation of the building materials deterioration and prolongation of the material exploitation. Different types of coatings with additional functions have been developed [2][3][4][5][6][7][8][9]. The interest for this area of research is enormous, but there are still areas that have not been scientifically covered.…”

“…The powder and the coated clay roofing tile samples were UV/VIS irradiated (EVERSUN lamp, intensity of UV-A and Visible light spectra were 0.8 mWcm -2 and 0.3 Wcm -2 , respectively). The distance between the UV/VIS lamp and the samples was 35 cm (20).…”

“…Moreover, the TiO 2 nanoparticles are embedded in the structure of a porous LDH avoiding the formation of macroscopic aggregates that may lead to the diminution of their efficiency. Furthermore, LDHs are stable supports that protect the TiO 2 particles from washing or erosion; they are non-toxic and present inexpensive materials (17)(18)(19)(20).…”

Synthesis of nanocomposite coating based on TiO<sub>2</sub>/ZnAl layer double hydroxides

ABSTRACT:The aim of this investigation was the synthesis of nanocomposite coatings based on Zn-Al layered double hydroxides (Zn-Al LDH) and TiO 2 . The Zn-Al LDH material, which acted as the catalyst support of the active TiO 2 component (in the content of 3 and 10 wt. %), was synthesized by a low super saturation co-precipitation method. The interaction between the Zn-Al LDH and the active TiO 2 component was accomplished by using vacuum evaporation prior to the mechanical activation and only by mechanical activation. The final suspension based on Zn-Al LDH and 10wt. % TiO 2 , impregnated only by mechanical activation, showed the optimal characteristics from the aspect of particle size distribution and XRD analysis. These properties had a positive effect on the functional properties of the coatings (photocatalytic activity and self-cleaning efficiency) after the water rinsing procedure. KEYWORDS: RESUMEN: Síntesis de un revestimiento nanocompuesto basado en TiO 2 / ZnAl hidróxidos dobles en capas.El objetivo de esta investigación fue la preparación de recubrimientos de nanocompuestos basados en Zn-Al hidróxidos dobles en capas (Zn-Al LDH) y TiO 2 . El material de LDH Zn-Al, que actuaba como catalizador del componente activo TiO 2 (en el contenido de 3 y 10 en peso.%), se sintetizó por un método de co-precipitación con baja sobresaturación. La interacción entre el Zn-Al LDH y el componente activo TiO 2 se llevó a cabo mediante el uso de la evaporación al vacío antes de la activación mecánica y sólo por activación mecánica. La suspensión final basada en Zn-Al LDH y 10wt. % TiO 2 , impregnada solamente por la activación mecánica, mostró las características óptimas desde el aspecto de la distribución de tamaño de partícula y análisis de XRD. Estas propiedades tenían un efecto positivo sobre las propiedades funcionales de los revestimientos (actividad fotocatalítica y eficiencia de auto-limpieza) después del procedimiento de aclarado de agua.ORCID ID: V.
